'Splain dude. Which registration points? Not the ones in the FGD I
assume, as those are supposed to be the lat/lon boundaries of the
map. Must be the registration points inside the geoTIFF, which are
used by these calls:
GTIFProj4ToLatLong ()
GTIFProj4FromLatLong()
GTIFImageToPCS()
GTIFPCSToImage()
Right now I expect that's where things might be screwed up. Can't
be _our_ code, right???
